Abstract (en)

A method for determining at least one membrane property of an analyte sensor (112) is proposed. The analyte sensor (112) comprises at least two measurement electrodes (114). At least one of the measurement electrodes (114) comprises at least one membrane element (122) having at least one membrane property. The method comprising the following steps:a) (134) generating at least one fast-transient voltage signal and applying the fast-transient voltage signal to the measurement electrodes (114) at an application time to;b) (136) measuring a first response signal U<sub>1</sub> at a first time t<sub>1</sub> and a second response signal U<sub>2</sub> at a second time t<sub>2</sub> with t<sub>0</sub> ≠ t<sub>1</sub> ≠ t<sub>2</sub>, wherein the application time t<sub>0</sub> precedes the first time t<sub>1</sub> and the second time t<sub>2</sub>;c) (138) determining a response signal U<sub>0</sub> at the application time t<sub>0</sub> by evaluating the first response signal U<sub>1</sub> and the second response signal U<sub>2</sub>;d) (140) determining the at least one membrane property by evaluating of the response signal U<sub>0</sub> at the application time t<sub>0</sub>.
